Black High pressure 12mm ID pumping hose (fire fighting stuff) from your local farm supplies type agency. (Elders, CRT, Murray Goulburn ect) About $13 a metre, cut your needed length and bang it on with a soft face walloper after immersion in hot hot water.
Yeap, that's the go Tim. That pressure stuff with the layers of strengthening woven throughout.
I had a Maico when I was a kid. Machined head for extra giddy up compression.
250, so no decompressor.
Lucky to have sand shoes or Jim boots to ride and kick with back then. So yeah, really liked a rubber on for comfort.
so easy to cut radial and lateral groves in it as well.
Machine a tapered leader up to press it on if you have to. They lasted heaps.
